Overview
The MP4012DS-LF-P is a constant current WLED driver IC from Monolithic Power Systems, housed in a 16-pin SOIC package. It supports boost, buck, buck-boost, and SEPIC topologies with an input voltage range of 8V to 55V. The device delivers up to 400mA output current at a switching frequency of 580kHz. Operating temperatures span from -40°C to +85°C. This component is marked as Not Recommended for New Designs (NRND), with the MP4013B recommended as the alternative for new designs.
Feature Summary
- Supports multiple converter topologies including boost, buck, buck-boost, and SEPIC for flexible LED drive configurations.
- Provides high brightness control via high-frequency PWM dimming and analog dimming capabilities.
- Includes comprehensive protection features such as overvoltage, thermal shutdown, and hiccup mode for open/short circuits.
Applications
- High-brightness white LED driving in portable devices
- General LED lighting applications requiring wide input voltage ranges
- Backlight drivers for displays
Procurement Notes
Verify the Not Recommended for New Designs (NRND) status before procurement, as this indicates potential future discontinuation. Confirm that the MP4013B serves as the designated replacement for any new design implementations. Ensure compatibility with existing legacy systems if continuing use. Check datasheet revisions for any specific handling or mounting instructions relevant to the SOIC-16 package.
Selection Notes
Select this component only for maintaining existing designs due to its NRND status. Consider the MP4013B for new projects as it offers updated features and longer-term availability. Evaluate the 8V to 55V input range against system power supply constraints. Verify that the 400mA output current meets the specific LED string requirements without exceeding thermal limits in the SOIC-16 package.
Part Context
This part belongs to the MP4012 series of LED drivers by Monolithic Power Systems. It is designed for versatile LED illumination tasks. The DS suffix denotes the 16-pin SOIC package variant. The LF-P suffix typically indicates lead-free composition and reel packaging. It is positioned as a legacy solution within MPS's portfolio, superseded by newer generations like the MP4013B.
Replacement Considerations
The MP4013B is the officially recommended replacement for new designs. Review the MP4013B datasheet for differences in input voltage range, topology support, and pinout compatibility before substitution.
